Measurement and Control System of Railway Vehicle's Brake Friction Testbed

The measurement and control system of urban rail vehicle's friction test-bed is a key part which has a direct impact on the brake shoe friction test results,while the accurate and precise detection and recording of the test data is a key component for the manufacture of vehicles.This paper introduces the mechanical structure design of the dynamometer testing,and the industrial design which is an intelligent monitoring and control system combining a control-computer,a multi-function data acquisition card and a special software development platform,this system is used in rail vehicles friction test.Thus,the real-time multi-channel data acquisition,the real-time display,the data processing,the post test data analysis and processing,the statements and test report generation as well as the printing functions could be all realized.
